TWO-PART HEEL.

Application filed January 2, 1923. Serial No. 610,103.

rlhis invention relates to two part heels and is in the nature ot a turtherdevelopment ot the construction shown inv applicants copending application, Serial Number 501,415, liled September 17, 1921.

In said copending case, in common with theA present application, there is disclosed a two part heel comprising a. central permanently `aixed portion having substantially a U-shape and a quick detachable tgl-shaped outer portion normally embracing said central portion and retained in place by suitable quick releasable fastenings.

The present invention consists inV an improved quick releasable fastening t'or` normally holding the detachable element of the heel in place and further consists in the curved shape ot the plate which is embedded in the removable element and holds the same in place whereby in use said pl-ate is under a stress tending to insure a firm seat ot the vdetachable element upon the shoe,

Figure 6 is a bottom view of the heel portion of a shoe to which the inner part olf the vimproved heel is shown fixed; j

Figure 7 is ase-:tional view similar to Figure 3 but showing an alternative form ot the invention;

Figure 8 is a detail view of the latch plate lor the center heel part' of the structure shown inv Figure 7.

'ln these views the reference character l designates the permanently allixed heel portion or a shoe which ordinarily is formed of leather. rlhe improved 'heel comprises substantially Eel-shaped inner and outer parts 2 and 3 respectively, the latter detachably embracing the former and both being preterably forme-d of rubber. The inner member 2 is permanently secured to the leather heel member l by screws lor other suitable permanent fastenings. The portion of said inner member close adjacent the heel member is reduced in width and also, at the back:l in length, as indicated at 2, to form a horizontally elongated neck portion. L5l is a sheet metal plate embedded in the part 2 reinforcingl the same andvfurther forming a latch member coacting with a sheet meta-l plate 6 embedded in the part 3 to hold the latter part in its position of use. The plate 6 is formed with a pluralityot holes Ga throughwhich the rubber above and below said plate is integrally connected and said plate is furthermore formed with a U- shaped central opening 6l proportioned to `embrace the neck portion Ll ci the part- 2. The portion of the plate G marginal to the opening 6b projects inwardly bey-ond the rubber body of the part 3- and in this projectingl portion,- struck-out tongues 7 are formed, one at each side or'v the opening t". lThe plate 5 is also formed with holes indicated at 8. providing,` for an integral connection between portions of the part 2 above and below said plate. At. each sid-e, the plate 5 projects laterally beyond the nec-k portion t just above the mainl body' ot the part 2 and these projecting marginal portions are formed respectively vith slots 9 in which the tongues 7 of the plate 6 engage when the parts 2 and 3 are in assembled relation. lVhen' said relation vis established the inner marginal 'portion ot the plate 6 engages above the outer marginal portion ot the plate 5 so that the latter plateand the detachable part 3 which it carries are held by the plate 5 from any downward movement relative to the part 2. Forwad or lateral movement of the part 3 relative to the part 2 is prevented by the embracing relation of the part 3 with respect to the aart 2. Rearward shiftingi ot the part S relative to the part 2 is prevented by engagement of the tongues 7 in the slots 9. it the lrear ends of said slots there are formed downwardly deflected lugs lO which act as stops engageable .by theiree ends of the tongues 7 to hold the part 3 in place, this relation being best illust-rated in Figure 3.

will be understood that as the part 3 is slid iorwarffllj.' into its position ot use, the

ate ti rides upon the plate the latter upwardly. Said nto the 13 Sfand en; ige the 10 as tht part i?. rescues its position ot Removal ot the outer element 3 may be etiected by springing the tongues 7 upwardly out ot the slots t) as by means ot a nail or some similar shaped instrument inserted through holes 11 termed in the part 2 in registration with the tree ends oisaid tongues, as best seen in Figures 1 and It will be noted that the lugs 10 are so inclined as to insure against binding et the tongues T on said lugs.

lVith reference to Figure 5, it will be seen hat the plate 6 which is preferably formed ot tempered steel is bowed upwardly slightly trom its center line to its lateral edges. However, in sliding the part 3 into engagement with the part '2, the inner marginal portions ot the plate (5 are upwardly deilected through engagement with the plate 5, as is best illustrated in Figure al. Thus the plate 6 in use is under a stress which holds the member 3 lirmly pressed against the leather heel of the shoe. rlhus there is avoided any crack or gap between the detachable part 3 and the fixed leather heel element 1, which would detract from the appearance of the shoe and also admit and retain moisture.

It is a further feature of the invention that the legs ot the outer part 3 are formed with slight upward projections at their tree extremities, as indicated at 12, in Figure 8, this increase otl thickness tending to maintain a tirm contact between said ends and the engaged under tace of the permanent heel member 1. For similar reasons the inner heel member has its top tace raised slightly at the forward end ot said member.

In the alternative form ot the invention shown in Figures 'T and 8 the improved heel comprises inner and outer members 13 and 1lreinforced respectively by plates 15 and 16 just as in the rst described form ot the invention. The latch tongues 1T upon the plate 16 in the alternative construction project, however, forwardly instead or" rearwardly and have preferably down-turned ends, as indicated at 1T, said ends being engageable in notches 1S provided in the plate 15. As in the tiret described 'form ot the invention, the outer member 14n is removable after the tongues 1T have been released Yl'roiu the notches 1S through inst tion ot a nail or the lili-e through suitable openings itl extended through the inner part. 12). YPreferably the plates reinforcing the parts 2 and 23 or 23 and 1li are copper plated as a preventative ot corrosion, and to insure adhesion ot the rubber to the metal. It will be noted that the inner heel member, shown in Figure 7, has lesser thickness than the outer member so that the lower sur- `tace ot the inner member lies above that Of the OUlCl PJGHIbQl.

What I claim as my invention isz-- 1. heel comprising inner and outer parts oi: substantially a U-shape, the latter embracing the tormer, the inner part being substantially permanently aliixed to a shoe, plates respectively embedded in said parts. the inner part having a neck portion ot re duced width, and the plate 'arried by the outer part having a central opening for embracing said neck, and having a marginal portion engaging above an outer marginal portion ot the plate carried by the inner part when the outer part is slid longitudiif-ally into engagement with the inner part, and spring tongues upon the marginal portions ot one otl said plates the other plate having slots in which said tongues engage to hold the two heel parts assembled.

2. )t heel comprising inner and outer U- shaped parts, the latter embracing the toriner, and plates carried by said partsl having portions overlapping to maintain said parts assembled, the plate carried by the outer part being transversely bowed and stressed reversely to its normal curvature through engagement with the plate ot the inner member to press said outer partv into lirm engagement with the shoe.

3. A heel comprising inner and outer substantially U-shaped parts, the latter .detachably embracing the former, and plates embedded in said parts having' portions projecting there't'rom and overlapping in the engaged position of said parts to maintain said position, one otl said parts being formed ot spring metal and being transversely stressed when in engagement with the plate carried by the other part to 'torce the outer part otl the heel into lirm engagement with a shoe.

#tf A heel comprising a substantially permanent part and a replaceable part, and plates carried by said parts having portions overlapping to maintain said parts assembled, the plate carried by the replaceable part being normally bowed, and stressed revers-ely to its normal curvature through engagement with the plate ot the permanent part to press said replaceable part upwardly against a portion oi said permanent part under the spring stress ot' said bowed plaie.

5. it heel comprising a substantially permanent part and a replaceable part, and metallic plates carried by said parts engageable to maintain said parts assembled, one o t said plates bodily forming a spring adapted to be stressed bodily through enfement with the other plate whereby said removable part is pressed firmly against said permanent part.

(. )t heel comprising a suliistantially perliti marient part and a Vreplaceable part, a metallic plate carried by one of said parts,
